SYMPTOMS

If in Visual FoxPro, you execute a FoxPro version 2.6 screen that has a CLEAR ALL command in the Cleanup code, the following error message appears:
Cannot clear the object in use.

CAUSE

As stated in the Visual FoxPro Help file topic for the CLEAR command:

CLEAR ALL within an event or method for an active control or object generates a Visual FoxPro error message. An object type memory variable cannot be released from memory when its associated control or object is active.

STATUS

This behavior is by design.

In FoxPro version 2.6, CLEAR ALL releases everything from memory except system memory variables.

In Visual FoxPro version 3.0, CLEAR ALL releases everything from memory except system memory variables and objects currently in use.
